1.5 OD 25mm Diameter UV-VIS ND Filter

Product Details Ideal for 250-700nm Sources Optical Densities Ranging from 0.3 to 3.0 TECHSPEC UV-VIS Neutral Density (ND) Filters are spectrally flat from 250 to 700nm and feature outstanding parallelism and surface characteristics. This combination of high tolerance and broadband performance makes these filters ideal for attenuating a wide range of sources. The filters are suitable for low power laser applications and can be stacked to obtain a variety of optical densities. TECHSPEC UV-VIS Neutral Density (ND) should have their mirrored side oriented toward the source at a 0° angle of incidence. Optical Densities of 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 available in a Pre-Loaded Filter Wheel . Note: Due to supply chain issues, our kits may be delivered with an alternative packaging solution in place of a wooden box. For any questions, please contact [email protected] . TECHSPEC UV-VIS Reflective Neutral Density Filter Kit Each kit includes 8 filters in optical density values of 0.3, 0.5, 1.0, 1.3, 1.5, 2.0, 2.5, and 3.0. The kit is ideal for determining precise system optical density requirements. Custom densities are available for OEM applications.
